CI: Changelog: Add new variable 'CHANGELOG_PROJECTS_SKIP', remove project list

The listed projects for the changelog are now supposed to be found
automatically. No need to list them anymore.
The 'SKIP' variable is mostly ment for custom projects, to filter out
unneeded projects from the changelog.

Changelog-generator: Add parameter to include all integrated projects

Before this, the changelog was generated on a given list of projects,
all using the same branch.
The new parameter now goes the the specified projects from the
parameters, and detects all integrated projects into this.
So normally you would specify one or two manifest projects, everything
else is automatically added to the list.

This also handles different branch names. As for example the kernel
branches are different, the integration branch is used instead of the
branch from the command line.
